Hi Oskar,

RAMINIT_SYSINFO is the config option to create the AMD sysinfo
structure in CAR above the stack. This is a way to get global data in
the romstage (heap like without any management). The space for the
data structure is allocated by the DCACHE_RAM_GLOBAL_VAR_SIZE config
and the pointer is setup in cache_as_ram_main.
